Influence of Welding Time and Environment Temperature on Electro Fusion Pipe Weld Properties

The paper deals with testing the influence of welding time and environment temperature on electro fusion pipe weld properties. Central composite design experiment with two factors in the pre-selected limits was chosen for planning the experiment. Results obtained by measuring the internal pressure were statistically analyzed. Analysis gave the response surface and the equation that describes the model dependence of internal pressure on the environment temperature and welding time.
